Great, Super Fun Game!!!
Few things i loved:
The background/floor, the way it moved in the areas you stepped very subtle but very nice, the light casted from the bullets to the floor was awesome!
The feeling of power and weakness at the same time, the game feel/game juice was great bullets felt impactful and satisfying to shoot. With the addition of the sfx and damage counters it was very well polish!
The difficulty scaling was spot on, easy to start playing and progress but just hard enough to lose just before the last upgrade. Which kept me coming back to play again. (6 runs in and im yet to break 4000+ and unlock the last upgrade lol)
Ambience was the perfect volume, it really set the feel of the game!
Overall this is a really great submission and I enjoyed playing it very much!
About to play another run!
Only issue is there no pause, i wanted give your game a good review/rating and write down what i liked and disliked so i might of missed a few(didnt have any dislikes after all, pause menu isnt really an issue)
